Agricultural Vehicle External Drive Control for Implement Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tractor operators face challenges in accurately positioning implements without repeatedly boarding and alighting from the vehicle, necessitating multiple personnel for precise alignment, and there is a need for safer and more convenient external control mechanisms.
Innovation Solution
An agricultural work vehicle equipped with electronically controlled transmission, external switches, and a controller that allows single-operator installation of implements through forward and reverse movement control from outside the vehicle, including sensitivity adjustment and emergency braking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver repeatedly boards and alights from the vehicle to check positions, then positioning accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The patent replaces the mechanical system of physically boarding and alighting from the vehicle with an electronic control system. External switches mounted on the vehicle body allow the driver to control forward and reverse movement from outside the vehicle, eliminating the need to repeatedly enter and exit while maintaining positioning accuracy through electronic actuation of the transmission system.
Solution Approach 2:
The patent introduces external switches as an intermediary device between the driver and the vehicle's transmission system. These switches serve as a mediator that transmits the driver's positioning commands to the vehicle's drive system without requiring the driver to be inside the vehicle, thus reducing time loss while maintaining control precision.
2Measurement precision
If two persons work together for precise alignment, then positioning accuracy is improved, but device complexity and operational requirements increase
Solution Approach 1:
The patent enables the driver to perform alignment operations independently through external switches mounted on the vehicle body. The driver can control forward and reverse movement from outside the vehicle without requiring assistance from another person, thus reducing operational requirements while maintaining alignment accuracy through direct electronic control of the transmission system.
3Ease of operation
If external switches are added for outside control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent designs external switches that serve multiple functions: they control both forward and reverse movement of the vehicle, and can be operated from outside the vehicle body. This multi-functionality allows a single external control system to replace multiple operational steps, improving ease of operation while minimizing the increase in device complexity through versatile switch design.
